Set loader-v4 program deployment slot at actual deployment

[pgarg66]

Problem

The program deployment fails when using loader-v4.

Summary of Changes

The truncate instruction sets the deployment slot for the program to the current slot when the buffer is being initialized. The deploy instruction checks if DEPLOYMENT_COOLDOWN_IN_SLOTS have elapsed since the last deployment. DEPLOYMENT_COOLDOWN_IN_SLOTS is set to 750, so the deployment fails (since the CLI sends truncate and deploy instructions in quick succession).

Taking a step back, the truncate instruction should not be setting the deployment slot when the buffer is being initialized. It should only be set at the time of program deployment.
